Aera Wallets API

WSP API changes

• Added new field (proprietaryData) will be received by the WLW, from the ECR/PSP and passed on the WSP in the Process WLW transaction init request and Process WLW transaction result request requests.

Functional changes to the WLW

• WLW is now integrated to the real Aera PSP.
• If a consumer tries to add the same payment instrument twice to the same wallet, WLW will no longer return an error. It will accept the new information and overwrite the existing payment instrument.

❗️

A re-onboarding for all wallet SDKs is needed for Get Wallet details to work. If not the WSP will receive this response:

Wallet details error response

{
  "responseInfo": {
    "message": "Wallet onboarding expired, new consumer onboarding required to get user info.",
    "responseCode": "68508",
